Awesome bag

This bag is the perfect on the go work/gym bag. The straps are not bulky, they are slender and properly padded for comfort. I love how the main access to the bag is up against my back, so no one can get into it behind you. It has an accessory pocket inside the bag on the side. It doesn't have a zipper on that little pocket, but that's ok. The space for the shoes is awesome too. This will be my go to bag for flying too; it'll be a perfect carry-on.

Great travel or gym bag

This is a great quality bag. Nice size for the gym or for traveling light. The ability to use with the shoulder strap or as a backpack is very handy. You’ll be happy with this bag. [This review was collected as part of a promotion.]

You’ll never look back

Makes trips to the gym so much more convenient and comfortable, because you aren’t carrying the weight on one shoulder, like most gym bags. You will not go back to the more traditional design. [This review was collected as part of a promotion.]

Good Value

Plenty of space for gyms stuff or ball stuff, for running to a game. Easy to carry, love the backpack option. Thought it might be weird but works perfectly. [This review was collected as part of a promotion.]

Great Multi-use bag

Works great as a gym bag. Also used as a carry on for a recent trip and was awesome. Backpack straps are very useful; keeps bag out of way and keeps hands free. Great purchase. [This review was collected as part of a promotion.]

A great backpack

I've been through several different backpacks and could never find the right one. This UA pack finally fits the bill. Lightweight and comfortable with all the pockets and storage compartments I need right where I need them. I use this for business and got the black on black which looks really sharp with the understated UA logos. As others have noted it doesn't stand upright but this is slimmer which is a trade-off I'll take. [This review was collected as part of a promotion.]

The product was exactly what I wanted and needed

I needed a new bag to carry my ball hockey ref gear and this has fit the bill perfectly. I love the back pack strap option as opposed to a single shoulder strap .The bag also has ample room to hold all my gear with room to spare. And the colour combination is awesome and stands out.

A couple problems, but not bad

I got this bag because I needed the size of a gym bag, but I like wearing a backpack. It works great for that. There's more than enough room for me to live out of it for the day with all my work clothes, gym clothes, and food. The shoe pocket even holds two pairs so that's nice. And I can still wear it easily on a motorcycle. That doesn't happen with a regular gym bag. Now for the complaints. I'm not a huge guy, my chest is about 42 inches around, but the chest strap still barely closes when I'm wearing a t-shirt. Forget about doing it up with a leather jacket on. If the bag is on the empty side, but you still have shoes in the shoe pocket and you want to wear it as a backpack, the shoe pocket is on the top side instead of the bottom side so the bag is top heavy and kind of uncomfortable. And lastly, the product description says the side pockets are breathable, but they look pretty solid to me. The only way they're letting air through is if you leave the zipper cracked open.

Bon produit - compact

Ce sac est très bon sac de sport compact et facile d'utilisation qui te permet d'avoir les mains libre avec le port sur les deux épaules. La poche faite pour les chaussure est top. Les caractéristiques du produit en ligne sont fidèle à la réalité. Si il fallait y ajouter quelques choses je dirait une petite poche à accès rapide (port sur le dos) pour pouvoir ranger clés papier et téléphone quand on sort de sa voiture par exemple. A quand des boutiques Under Armour ou bien des points de vente pour pouvoir tester les chaussures et vêtements lorsqu'on ne connait pas sa taille chez vous ? A quand les produits "rugby" pour les femmes ? Car en tant que joueuse en Fédérale 1 c'est pas toujours simple de s'équiper avec des produits qui tiennent la route et qui on de l'allure, car oui même sur le pré c'est plus sympa de se sentir bien dans ses vêtements.

Sehr robuste und praktische Tasche

Als Seesack zum Fliegen mit Handgepäck gekauft. Passt perfekt und angenehm zu tragen. Ausserdem wasserfest. Perfekt zum segeln.
